On the Chorus Platform side, we power Chorus.ai, a Conversation Intelligence platform that processes and analyzes an enormous volume of sales calls to surface insights on deal health, risk, and next steps for sales managers.\nThis is a role for an engineer who is energized rather than daunted by breadth: high-volume JVM streaming systems on one side, Python distributed services and third-party integrations on the other, with the seniority to make architectural calls across both and the humility to ramp quickly on whichever stack is less familiar.\nWhat you will do\nDesign, build, and deploy complex distributed systems across both domains\nBuild high-volume streaming data processing services using Kafka to handle millions of engagement data points per day\nDesign and implement real-time engagement-to-CRM entity mapping systems\nDevelop robust Java-based microservices that integrate tightly with data storage solutions\nBuild and own Python backend services and RESTful APIs handling millions of customer requests per day\nBuild third-party integrations with major conference providers using their SDKs\nOwn customer-facing aspects of the product end to end, from design through production operation\nDrive architectural decisions that span both areas - data modeling, service boundaries, performance optimization\nHelp define and promote engineering best practices: design, documentation, code review, monitoring, observability\nMentor and train engineers across the team, raising the technical bar in both domains\nAct as a technical point of contact across teams and personas, translating ambiguous product needs into concrete systems\nWhat you bring\n7+ years of industry software development experience; B.S. in Computer Science, Mathematics, Software Engineering, or equivalent\nStrong hands-on experience in both Java and Python in production settings (deep expertise in one and working proficiency in the other, with a track record of ramping fast on new stacks)\n3+ years building distributed systems and microservices at scale\n3+ years with streaming data platforms (Kafka strongly preferred)\n4+ years of cloud experience (AWS/GCP) - a must\nSolid experience with both SQL and NoSQL stores (Mongo, Elasticsearch)\nStrong grasp of RESTful API design standards and event-driven architecture\nExperience with CI/CD, package management, and release cycles\nStrong architectural design skills while remaining deeply hands-on\nExcellent communication skills in English and the interpersonal range to collaborate cross-functionally\nDemonstrated leadership: mentoring engineers, driving projects independently, taking initiative without being asked\nBonus points\nExperience with CRM systems (Salesforce, Microsoft Dynamics) and integrating data services with them\nApache Kafka ecosystem depth (Kafka Streams, Connect)\nSpring Boot microservices deployed to cloud\nExperience with conferencing platform SDKs (Zoom, Teams, Webex, Google Meet)\nFamiliarity with data pipeline orchestration tools\nMonitoring and observability tooling for streaming systems\nData modeling and schema design\nPrevious experience in B2B data, sales intelligence, or conversation intelligence domains\nActual compensation offered will be based on factors such as the candidate’s work location, qualifications, skills, experience and/or training.
